Sun Protection Factor Testing

Overview

Sun Protection Factor (SPF) is a number determined experimentally by exposing a subject to a room's UVB spectrum of simulated midday sunlight. The SPF of the tested product is determined by dividing the amount of light that reddens sunscreen-protected skin by the amount of light that reddens unprotected skin. Daji Belle offers all standard SPF methods to determine the SPF of test products, including but not limited to static testing, water resistance testing, and UVA and UVB testing in compliance with all global regulatory agencies.

Specific Services We Offer

• Determination of SPF

We perform in vitro testing in accordance with internationally accepted methods to accurately determine the SPF value of sun protection products. Our experts measure the amount of UV radiation that passes through the product to determine its level of protection.

• Critical Wavelength Measurement

We determine the critical wavelength, which indicates the overall UVA protection of the product. This measurement is critical because UVA rays are associated with aging, skin damage, and increased risk of cancer.

• Water Resistance Testing

We perform tests to evaluate the water resistance of sunscreens to ensure that they maintain their stated SPF after exposure to water or sweat, in compliance with regulatory requirements.

• Broad-Spectrum Evaluation

Our services include evaluating the broad-spectrum protective properties of sunscreens to verify their ability to protect against UVA and UVB rays.

Further services:

In addition to SPF testing, we offer a range of related services to support the development and regulatory compliance of sun protection products:

• Light stability testing: Evaluate the stability of products under light to ensure they remain effective in the sun.
• Formulation Evaluation: Consulting and testing support to optimize sunscreen formulations for improved SPF and broad-spectrum protection.
• Label Claim Validation: Verification of product label claims to ensure accuracy and compliance with their representation of sun protection properties.

Deliverables

• Detailed test reports outlining the SPF value, critical wavelength, water resistance, and broad-spectrum assessment results.
• Expert recommendations and guidance on improving product performance, if necessary.
• Assurance that their sun protection products meet regulatory requirements and provide accurate sun protection information to consumers.
